udy Purpose
e of Colorado (State) has an allocation of 10,460 AF of A -LP Project water (State Water) and is
sting the potential for marketing this water to local water providers in southwestern Colorado.
udes identifying the quantity of water that water providers in the vicinity would be interested in
ing, how much these providers would be willing to pay to purchase this water, and when these
would anticipate needing this water. This information will also be used to assist the State in
ling how much water from the State's A -LP Project allocation could be used for Colorado River
t compliance purposes and meet other potential uses identified by this study. While the State
ty to sell this water if it is needed by another Colorado water user, it is important to note that the
the responsible party for negotiating the purchase contract with Reclamation.
The A-L Project is located in southwestern Colorado, within the Dolores /San Juan /San Miguel ( DSJSM)
Basin. he DSJSM Basin includes Archuleta, Dolores, La Plata, Montezuma, San Juan, San Miguel, and
portionE of Hinsdale, Montrose and Mineral counties. For the purposes of the A -LP Project Water
Markets ig Supply and Demand Study (Study), Brown and Caldwell focused on water demand needs for
La Plata and Archuleta counties because of proximity to Lake Nighthorse, see Figure 1.2.
To assis the State with this water supply and demand study, Brown and Caldwell was contracted by the
Colorado Water Conservation Board (CWCB), La Plata Archuleta Water District (LPAWD) and
Southwestern Water Conservation District (SWCD) to complete the following tasks.
1.2.1 Previous Study on A -LP Water
Brown a id Caldwell was contracted in November 2009 to identify the capital costs of A-LP Project Water
for the ate and to investigate water providers that may have interest in purchasing any of the State
Water. Gapital costs are composed of the actual capital costs of construction plus interest during
constru ion (IDC), until Reclamation transfers the A -LP Project from "construction" to "operations and
mainten nce" (0 &M) status. At the time of the first study, it was anticipated that the 0 &M phase would
begin so etime in 2011. This change in status will be a formality which will stop the accrual of IDC. At
that poi , IDC will become a capitalized cost.
Addition Ily Brown and Caldwell reviewed available planning data to identify water providers with
potential need for additional water supplies in the study area. Brown and Caldwell also interviewed
identifie water providers to understand future plans and need for additional water supply. This
informat n was summarized in both tabular and map formats, along with a listing of local providers.
